Addressing adherence before adding more therapy in severe asthma

What is it about?

This randomised trial compared two strategies to improve adherence and inhaler technique in patients with severe asthma. Feedback to the individual on inhaler adherence and technique improved outcomes. Importantly, almost 30% of people did not become adherent, even during this study when people knew that they were being assessed for adherence. This has implications for the use of add-on therapy in severe asthma, as roughly half of the poorly controlled people at the end of the study had been sufficiently adherent.

Why is it important?

Addressing adherence and inhaler technique are important aspects of clinical care. Even under close supervision poor control was more likely to be poor adherence than refractory asthma.
